Designed to crown door and window openings in large-scale architectural projects, the P14D60D400VI model is a decorative structural element that adds a classic character to your buildings. Enhancing the sense of depth in wide transition areas and facade designs, this round curved arch balances the overall geometry of the space to create an aesthetic harmony.
The product boasts a grand scale, measuring 140 mm in width, 4770 mm in arc length, and 2385 mm in vertical height. Manufactured from high-density rigid polyurethane, this model achieves the hardness of wood with a density of 150-220 kg/m³, yet is significantly lighter than traditional plaster or stone alternatives. Thanks to its closed-cell structure, its water absorption rate is below 1%, providing high resistance to moisture, rot, and mold. Additionally, it fully retains its shape under temperature fluctuations ranging from -20 °C / +70 °C.
Looking at its visual design, the arch features stepped and circular contours on its smooth surface. These simple yet distinct profile details bring dynamism to the facade through the play of light and shadow. From heavy restoration projects to modern villa designs, it serves as a transition element that ensures visual integrity without disrupting the facade.
Boasting a wide range of applications, this model is highly preferred for exterior windows of prestigious residential projects, grand villa entrances, hotel lobbies, and high-ceilinged hall transitions. Assess water and moisture exposure using the product technical data, surface finish and installation details.
During installation, Polure Polfix adhesive should be applied to the cleaned surface, and due to the product's dimensions, mechanical fastening with screws is mandatory. While the factory-applied primer provides an excellent base for the topcoat, applying an additional primer for paint manufacturers' own system warranties is left as an optional choice for the user. For outdoor applications, a UV-resistant paint must be applied to protect the material from sun damage.
- This round curved arch model is an excellent molding complement for framing wide arched windows and main entrance doors
- Suitable for both interior and exterior use, this product acts as an aesthetic crown above windows on the facades of large-scale villas
- Indoors, it is ideal for designing grand transition portals that separate spaces, particularly in high-ceilinged living rooms, wide corridors, hotel lobbies, and restaurant transitions
- It can be painted in colors matching the architectural style of the building to ensure facade integrity
- The application surface must be completely cleared of dust, dirt, and moisture
- The joints of the curved parts are precisely measured and aligned
- During installation, Polure Polfix polyurethane adhesive is applied to the back surfaces
- Due to the large dimensions and safety requirements of the product, mechanical fastening with screws is mandatory in addition to the adhesive
- Screw heads and joint seams are filled with exterior-grade putty and smoothed with 180-220 grit sandpaper
- Before the topcoat, an optional extra primer can be applied according to the paint brand's recommendation; the installation is then completed with at least two coats of paint
- Since the product is moisture-resistant, it can be easily cleaned with a damp cloth
- Abrasive chemicals and stiff brushes should not be used during cleaning
- For exterior applications, the painted surface should be inspected periodically and repainted if necessary to ensure the paint continues to protect the material from sunlight
Can the product be used outdoors, and is it weather-resistant?
Yes, the product is fully suitable for exterior use. Thanks to its closed-cell structure, it has low water absorption (below 1%), making it highly resistant to rain and moisture. It retains its shape in temperatures ranging from -20 °C / +70 °C. However, to protect it from sunlight outdoors, it must be painted with a UV-resistant exterior paint.
Which adhesive should be used during installation?
Polure Polfix polyurethane adhesive, which offers high bonding strength, should be used for installation. Silicone-based adhesives are not suitable for this product group. Additionally, due to the product's dimensions, mechanical fastening with screws is mandatory for safety reasons.
Does the product come pre-painted from the factory, and can I paint it directly?
The product is shipped from the factory with a special white primer coat. This primed surface prepares the product for the topcoat. However, if paint manufacturers recommend an additional primer under their own system warranties, applying an extra primer after installation and before the topcoat is optional and left to the customer's preference.
What are its advantages compared to plaster or wooden arches?
Plaster arches are very heavy, fragile, and difficult to install. Wood, on the other hand, can absorb moisture over time, rot, or crack due to insect infestation. In contrast, the polyurethane arch has the hardness of wood with a density of 150-220 kg/m³, yet it is extremely lightweight, durable, highly resistant to rot, and suitable for humid conditions.
Can the dimensions of the arch be modified or cut?
The P14D60D400VI model is molded in standard dimensions of 140x4770x2385 mm. However, during installation, dimensional adjustments can easily be made to suit the project by cutting the ends with a saw; the cut surfaces can then be sanded and puttied.
